How to disable images using Outlook express This has been an issue to few folks. Basically what happens is that when your receive your email, you get lot of junk mail which are formatted with HTML etc. Some of them are not suitable to your taste but also take some time to load. There are some alternative ways to block the load of images but each has its advantage and disadvantages: 1) Disable images in IE as it also affects OE 2) If you're running a firewall with rules make a rule that blocks OE's access to port 80. That way it can't get the images it needs. 3) There is a utility called DetachXP <http://www.mcdev.com/detachxp.htm>. This program could be used to apply the blocking even though its primary aim is to allows you to access these blocked files in Outlook 2002, without editing the Windows Registry manually 127.

All right here are the instructions: step 1: Open a text editor, such as Notepad, and type the following lines into a new document: (assuming the printer you wish to use is connected to printer port #1). CD %1 DIR >LPT1 Save the two-line file into your Windows\Command folder, and call it PRINTDIR.BAT. step 2: Find the file in Explorer, right click on it, and select Properties. Click on the Program tab, turn on the Close on Exit option, choose Minimized from the Run list, and click Ok. Next, run the Registry Editor (REGEDIT.EXE) by going to START-RUN and type regedit and navigate to [\HKEY_CLASSES_ROOT\Directory\shell]. Select New from the Edit menu, and then select Key.

Once console is loaded do enter this command FIXMBR /device/harddisk0 (where harddisk0 refers to C: drive where WINDOWS XP is installed by default). This would fix your master boot record to default XP boot. By the way FIXMBR command is only available from recovery console. What to know more about FIXMBR, visit Microsoft TechNet site <http://www.microsoft.com/technet/treeview/default.asp?url=/TechNet/prodtechnol/winxppro/proddocs/bootcons_fixmbr.asp> If you have followed the instructions correctly, you are done. 133.

Download a freeware called ResourceHacker by going to http://www.rpi.net.au/~ajohnson/resourcehacker <http://www.rpi.net.au/%7Eajohnson/resourcehacker> 3. Now, lauch resource hacker and locate your explorer.exe by going to c:\windows. Now go to String Table>37>1033. This is where the START text is located. Change it whatever you would like.... 4. Once done with the changing START button text, click on the button called "Compile Script". Now its time to save the changes. Important: Save the file as explorer_modified.exe (or something similar). You can not save it as explorer.exe as file is in use as you are exploring the directories etc etc. 5. All right, reboot the computer and boot into safe mode in command prompt environment (at boot time press 'F8' a few times...) and log in as administrator. 6. Now all that you need to do is to copy the modified explorer file to original one. Type this at command prompt "copy c:\windows\explorer_modified.exe to c:\windows\explorer.exe" (without quotes) 7. Reboot your computer as you would normally do. If you have followed the steps correctly, you should have new explorer by now. 135. How to disable screen saver in Windows XP ? One of the easiest things that you can do to remove screen saver is to simply select none from the Screen Saver tab of Desktop properties window. This should help. Doing this would be all that most of us would ever need for those few who want to go one more level, here is what you can do. Windows has a default screen saver called login.scr, which runs even if no screen saver has been selected. There is a potential security risk here as login.scr can be removed and replaced with malicious screen saver with system priviledges. To resolve this, Open registry and navigate to [HKEY_USERS\.DEFAULT\Control Panel\Desktop] and look for the data key "ScreenSaveActive". Setting its value to 0 would disable screen saver (you can always enable it by setting it back to 1). You may as well change the login.scr that is goes as the value of data key 'SCRNSAVE.EXE' .Try clearing out the value for 'SCRNSAVE.EXE' to completely remove the screen saver or replace it with some thing of your own. 136.
